In 宝石がいっぱい！(Romanization: Houseki ga Ippai!) players take turns flipping over cards in search of valuable gemstones. On each player’s turn, he or she turns over one face down card in the field. Depending on the revealed card, the player may be able to collect a gemstone, gold, or part of a fossil. They may also be able to steal a card from one of their opponents if they find the thief card. After all eleven gemstones have been collected, the game ends. The player with the highest total of valuable cards wins.
